Not a link to DOOM. DOOM.

Most "on-chain" games store a URL. This stores the game. Every byte of the engine and the shareware levels sits inside the data field of a Solana transaction, forever, on every full node in the world.

Root 1 transaction 2qQD…vPsc

Index 11 transactions 60 signatures each

Game data 577 transactions 3,895 bytes each

4,096 bytes per transaction since Solana's v1 format went live on mainnet on September 15, 2026. Before that: 1,232. DOOM would have needed 1,850 transactions. Now it needs 588.

0.012 SOL total network fees to write the entire game. Storage in transaction data has no rent. It never expires.

0 servers between you and the game. The page asks an RPC node for the transactions, checks the SHA-256 against the root, inflates the gzip, and boots the WebAssembly. Even the boot script comes from the chain.

Rip and tear. Then ape.

The game is the proof. The coin is the ticket. Three steps, no wallet drama.

1
Get a Solana wallet. Phantom or Solflare, on phone or desktop. Fund it with SOL from any exchange.
2
Copy the contract. Only from this page or the pinned post on X. Anything else is a fake.
3
Swap SOL for $DOOM. Paste the contract into pump.fun or Jupiter, pick your size, confirm.
